Status changed to 'Confirmed' because the bug affects multiple users.

The fix is trivial:

https://gitlab.gnome.org/GNOME/tracker-miners/-/merge_requests/511

But it begs the question: Why do we keep having to fix these crashes one by one over such a long period of time?

> Why do we keep having to fix these crashes one by one over such a long period of time?

In this case I think this is a consequence of the allow-list nature of the seccomp filters - as glibc changes to implement various functions via different primitive system calls / or the kernel changes to add new system calls and glibc starts to make sure of these, the seccomp filter needs to be updated to take this into account.

tracker-miners (3.7~rc-1) experimental; urgency=medium

  * New upstream release
  * Re-enable landlock feature
  * Do an additional build without landlock for build tests only
  * Skip bmp-basic-1 test on big-endian architectures:
    it is a new test failing there

Alex, it was more of a rhetorical question. I understand the security design, it's more a complaint about poor upstream software engineering when we must suffer and fix the same crashes repeatedly. It's security vs usability.

[Alex Murray (alexmurray)]

Ah fair enough ;)

No it's not released yet.

I've seen this on today's daily release. Fresh installation on Yoga 7i Gen 9 (Intel 155H)

[Robert Los (robert-robertlos)]

This is a new computer with the following specs:
MB: MSI X670E tomahawk
proc: AMD 7950X
VIdeo: Nvidia 4070 ti Super
Mem: 128 GB Kingston fury 6000

Installed Ubuntu 24.04 daily because 22.04 did not work with this hardware and the latest nvidia driver

Downloaded a day or two ago.
Trying on Dell T7920 Workstation.

Should I download a new ISO?

[corrado venturini (corradoventu)]

Just wait for fix, is already in proposed.

[Daniel van Vugt (vanvugt)]

Actually it's in 'release' now. But you may not get it automatically while 'updates' points to an older version.

Just wait for any version 3.7.x
